Essential Aspects of Mirror Backing

The selection of mirror backing material hinges on several essential aspects, including:

Reflectivity: The backing material must not interfere with the mirror's ability to reflect light.
Adhesion: The backing must adhere securely to the mirror's surface, preventing delamination or detachment.
Moisture resistance: The backing must protect the mirror from moisture penetration, which can lead to corrosion and deterioration.
Durability: The backing must withstand environmental factors, such as temperature fluctuations and chemical exposure.
Safety: In the event of breakage, the backing should prevent sharp edges or broken glass from posing a hazard.
